Over the past year, Cambodia’s ruling party, the Cambodian People’s Party (CPP), has dramatically increased its pressure on its political opponents and civil society. Democracy in Cambodia has always been fraught, and elections are not completely free and fair. But the current crackdown is much greater in scope, and far more concerning, in part because it is being enabled by American apathy.

Prime Minister Hun Sen, East Asia’s longest-serving non-royal ruler, has used his power to silence critics and close outspoken media outlets, including one independent newspaper, the Cambodia Daily. The CPP has also expelled the National Democratic Institute, a US-based nonprofit that focuses on rights and democracy, and detained political challengers. Kem Sokha, who co-headed the main opposition group, the Cambodia National Rescue Party (CNRP), was arrested in September on dubious treason charges. The other main opposition figure, Sam Rainsy, remains in exile in France.

But in recent weeks, Hun Sen has increased the pressure, essentially ending Cambodia’s shaky attempts at democracy. Earlier this month, a court dominated by CPP allies dissolved the CNRP. As a result, the party will most likely be unable to contest national elections next year, all but ensuring that Hun Sen will win another term as prime minister. The ruling could also help enable Hun Sen to eventually hand power to another family member. Fearing for their lives, around half of the CNRP members have left Cambodia.

Hun Sen has hardly been shy about his slide towards what the Cambodia Daily, on its last day of publishing, termed a ‘descent into outright dictatorship’. In fact, Hun Sen, like other Southeast Asian autocrats, now seems to believe that he has political carte blanche, given the low priority that US President Donald Trump has placed on human rights.

In the past, Western pressure had managed to keep Hun Sen in check. Foreign aid, including from the US, accounts for as much as 40% of Cambodia’s national budget. And, while President Barack Obama’s administration did expand cooperation with Cambodia, it also repeatedly raised the issue of human-rights abuses with Hun Sen, including during a tense visit by Obama to Phnom Penh in 2012.

The Trump administration has rolled back this pressure, and then some, by downplaying human rights and democracy promotion. In an address to the United Nations General Assembly in September, Trump made clear that his priority would be sovereignty rather than rights. Secretary of State Rex Tillerson, meanwhile, has even reportedly considered removing democracy promotion from the State Department’s mission.

Hun Sen recognised this shift almost immediately. In February, he compared his disdain for Cambodia’s media to Trump’s distrust of the mainstream media in the US. And although lower-ranking US officials, including the senior director for Asia on the National Security Council, have met with their Cambodian counterparts to press them on rights issues, Trump has said nothing negative about Hun Sen’s actions. In a speech in early November, Hun Sen essentially praised Trump for his indifference and non-interventionism.

Philippine President Rodrigo Duterte, meanwhile, held a friendly phone call with Trump back in April. Trump praised the Philippine leader for his brutal, lawless ‘war on drugs’, in which, according to Human Rights Watch, more than 12,000 people have died.

During Trump’s visit to Manila in November, Duterte serenaded him with a song, and then Trump laughed when, in a joint appearance, his counterpart blasted the media, calling them ‘spies’. (The Philippines is one of the most dangerous countries in the world to be a journalist, according to the Committee to Protect Journalists.) Trump later claimed that he briefly mentioned human rights to Duterte, but a Philippine government spokesperson said the two had not discussed rights issues.

As Hun Sen, Duterte and others have shown, the new US approach fosters impunity for autocratic leaders. Although other donor countries, such as Canada and France, have at times spoken out against Hun Sen’s abuses, the US government, as the actor wielding the most leverage, has historically led the charge.

But the Trump administration’s see-no-evil approach hinders other countries’ ability to promote rights and democracy. For example, Canadian Prime Minister Justin Trudeau, in his own bilateral meeting with Duterte last month, did raise concerns about the drug war in the Philippines. But without US support, Trudeau’s pressure lacked credible measures.

Trump’s policies are placing America’s long-term interests at risk. As in Cambodia, many of Asia’s strongest supporters of democratic change are young men and women. Opposition parties in Malaysia, Cambodia and other Southeast Asian countries attract a high share of young people, as do many of the media organisations and civil-society groups now under pressure. And, most important from the standpoint of national interest, the US has built its strongest partnerships in Asia with other democracies.

Policies that ignore human rights and democracy will not benefit the US or the region. An ‘America First’ approach that disregards these issues—in Cambodia or elsewhere—will only leave the US weaker in the end.
